IMPROVEMENT IN FLOUR-BOLTS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOSEPK Gr. HUMES, of Gravios Mills, in the county of Morgan, and State of Missouri: have invented a new and improved Reel for Bolts; and I do hereby declare that the following is a full, clear and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a new and useful improvement in the construction of reels for bolts.

The object of the invention is to admit of the bolting-cloth being stretched uniformly at the inner sides of the ribs of the reel, whereby all obstructions to the free passage of the flour through the bolting-cloth are avoided, and the flour separated from the bran and coarse portions of the meal by a sifting process solely, and not. by the raising of the meal and falling of the same within the bolt as it rotates, as is now the case, owing to the ribs, which are at the inner side of the bolting-cloth, catching the meal and operating upon it'in that. way, and which causes more or less fine bran to be forced through the bolting-cloth, that would otherwise pass out with the coarser portions at the tail of the bolt. v v

The bolting-cloth also is liable to become choked or clogged up by this raising-and falling of the meal.

In the accompanying sheet of drawings Figure 1 is a side view of my invention, partly in section.

Figure '2,'a transverse section of the same, taken in the line :0 x, fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the shaft of the bolt, on which two hubs or bosses, at a, are keyed.

To these hubs or bosses radial arms, I), are permanently attached.

Through each arm 1), near its outer end, an eyebo1t,c, passes. These eye-bolts are adjustable, to compensatc for any inequalities in the securing of the strips of muslin to the cloth, and the bolts serve as guides for rods B, the inner ends of vhich are fitted and allowed to turn freely in the peripheries of the hubs or bosses a a,

These rods also pass transversely through the v-shapcd ribs O of the bolt-reel, and through metal nuts 12, attached to the outer sides of the ribs.

Rims D are attached to the ends of the ribs 0, and these rims D, ribs 0, and the hubs or bosses a, arms 6, and rods B constitute the reel of the bolt, the threelast-named parts comprising whatIterm adjustable spiders.

E is the bolting-cloth, attached to the inner surfaces of the ribs C as follows:

First, divide the bolting-cloth into as many equal parts as there are ribs in the reel; then take strips of muslin, or other suitable material, e and sew through the centre of the strips and the equidistant parts of tho bolting-cloth, protecting the holes through which the rods B pass with leather, f, sewed around them, and then tack each side of the muslin to each side of the rib, insert the rods B, and, by turning them, expand the reel until the cloth is sufficiently tight, ahd attach the rims D to the ends of the arms C, and to which rims tack, or otherwise fasten, the ends of the bolting-cloth.

By this arrangement it will be seen that the interior of the bolting-cloth has an unobstructed surface, so that the meal will be. sifted through the bolting-cloth. The former will not be'caught by the ribs and raised by them nearly to the top, and then allowed to drop or fall upon the bottom, as is the case when the ribs are at the inner side of the bolting-cloth.

It will also be seen that, by turning the rods 13, the ribs U may be drawn 0r sprung outward, sufficiently to cause the bolting-cloth to be strained as taut as necessary, so that the bolt may always be kept in perfect working order.

I claim as new, and desire to secure by Letters Patent- The construction and arrangement of the radial arms 6 ailix'ed to the bosses at, the adjustable screw-bolts B, and adjustable eye-bolts 0, whereby the bolting-cloth is strained radially and longitudinally, as herein described, for the purpose specified.
